Bali’s September 2026 Warning Highlighted Drought Risk, Not Confirmed Floods

Denpasar — Bali’s official records show an early warning for the second ten‑day period of September 2026 that highlights dry‑season conditions and meteorological drought risk, not a specific district‑level flood warning for 20 September 2026. Available national and provincial situation reports do not document any confirmed flood impacts in Bali for that date.

The core advisory on “Peringatan Dini Cuaca/Iklim Dasarian II September 2026 Provinsi Bali” was issued by the provincial disaster management agency BPBD Bali from Denpasar on 10 September 2026. According to BPBD Bali, Bali remained in the dry season during Dasarian II (11–20 September) and the main concern was meteorological drought and related hydrometeorological hazards. The agency urged residents to conserve water and remain alert to drought and fire risk, while monitoring official updates from BMKG and BPBD.

What BPBD Bali’s warning covers

BPBD Bali’s early‑warning note sets out a 10‑day forecast for 11–20 September 2026. The agency reports potential light rain across all nine regencies and cities—Badung, Denpasar, Gianyar, Klungkung, Tabanan, Jembrana, Bangli, Karangasem and Buleleng—during three sub‑periods: 11–13, 14–16 and 17–20 September.

Both BPBD Bali and local media emphasise that this limited rain potential does not mark the end of the dry season. BPBD Bali notes an early warning for meteorological drought for 11–20 September and explicitly states that there is no early warning for high rainfall in that period. In parallel coverage, a Bali news outlet quotes BPBD Bali’s head, I Gede Teja, stressing that residents should remain vigilant for drought and fire, despite the chance of light showers.

The September advisory therefore describes regional weather and climate conditions and associated drought risk, rather than forecasting widespread flooding.

What the national situation report shows

At the national level, the disaster management agency BNPB published a situation update on 10 September 2026 covering events recorded between 9 and 10 September. The report summarises floods, land fires and other incidents in several Indonesian provinces and notes that floods and wildfires remained priority concerns for central and local governments.

In the publicly available text, BNPB does not report a flood incident in Bali for that 24‑hour period. The focus is on other regions facing active floods or large‑scale fires. This absence in one national snapshot, however, cannot by itself prove that no minor or localised flooding occurred; it indicates only that BNPB did not highlight Bali flood impacts in that particular report.

Flood risk versus flood impact

Disaster agencies distinguish between a regional forecast and a local impact report

BPBD Bali’s September 2026 advisory and accompanying media coverage identify dry‑season conditions, potential light rain and heightened drought and fire risk. They do not provide measured rainfall totals, river levels, drainage performance or inundation data for specific Bali districts on 20 September. Likewise, the BNPB national situation update does not supply Bali‑specific flood measurements or damage reports for that date.

For residents and visitors, the practical implication is that a provincial outlook for light rain during the dry season is a signal to monitor conditions and follow official channels, but it is not evidence that a flood event occurred. Travel safety and local planning decisions are best based on current, location‑specific advisories or impact reports issued by BPBD Bali, local governments and BMKG when hazards escalate.
